Dankmar Adler (1844-1900) was a German-born American architect and engineer in Chicago, Illinois. Adler worked with Augustus Bauer, Ozias S. Kinney, and Edward Burling, but he is best known for his partnership with Louis Sullivan from 1880 until the mid 1890s. In his various partnerships, Adler was instrumental in rebuilding much of Chicago following the Great Chicago Fire in 1871 and he is considered a leader in the Chicago school of architecture.
